Package and Appearance
Silverstone's package design and the power supply itself always come in black. We would not expect to get a red power supply soon, similar to those from PC Power & Cooling for example. In the box we found the standard stuff like screws, a manual, power cord, and a high quality bag in which the user can store unused cables.
The power supply is quite long for a 700W unit and after opening it up we will see why this is the case. The fan is located quite close to the back, which is unusual for power supplies as now there is a big part of the power supply inside that will not get as much direct airflow. The installed fan is 120mm, which is also common with Silverstone even though many of the competitors have changed to larger fans. The problem is that there are quite a lot of patents on larger fans and Silverstone might not want to pay royalties, especially when a 120mm fan is doing just fine.
The whole rear is covered with small holes which allows for very good air circulation as the exhausted air has plenty of space to get out of the power supply. On the other side - which will be inside of the PC case once the power supply is installed - we find the modular cable system. It sticks out a bit since Silverstone designed it with a small box there. We will see later that the jacks for the cable management are very long, so Silverstone chose to cover the jacks with this small box. A detailed description of the jacks is visible on the bottom of the power, and it will remain visible after installation. This makes sense of course; nobody would be able to see the sticker if it were on top of the casing (except for in cases with a bottom-mounted PSU).
The harnesses are partly sleeved with a black mesh that keeps the mess of cables tidy. All of the cables are detachable, but we have to mention a flaw we noticed at the connection between PSU and cables. The jacks feel quite loose and move around when you attempt to detach cables. You will need to press down on the little lever at the connector, which is not always easily accessible, and this makes it difficult to unplug a harness. Silverstone should try to improve this area in the next version.
There are sufficient connectors on the harnesses, but there could have been maybe one more on each. There are currently three connectors on each SATA and Molex. The distance between the connectors might work in some cases, but normal systems have their hard drives much closer than 10" apart. We cannot see a benefit in having such a large gap between the connectors. There are four 6-pin PEG connectors for a decent SLI/CF setup and an additional 8-pin PEG connector. Only a 3-way 8800 Ultra setup would require additional PEG connectors at present.
The installed fan responsible for cooling this unit is a 120mm so called rifle bearing fan from Protechnic with the part number MGA12012HF-025. The fan control keeps this fan at a nice maximum of 1600RPM during operation. Even at maximum speed, the noise from this PSU will be quite low.
